How does Chapter 28 differentiate the role of a Sadguru from that of a father?

Chapter 28 presents a powerful comparison to illustrate the unique and elevated role of a Sadguru like Sai Baba. It states that while a father is responsible for giving birth to the physical body, this very birth inevitably leads to death. In contrast, the Guru's compassion is described as "additional" because he works to remove the entire cycle of both birth and death for the disciple. The chapter further defines a Sadguru as one who is proficient in both Shabda-Brahma (the divine word) and shows signs of Para-Brahman (the Supreme Being), possessing the essential quality of being able to impart teachings.
